SPECIFICATION forming part of Letters Patent N0. 737,159, dated August 1903.

Application filed May 16, 1903. Serial No. 157,353. (No model.)

To all whom t may concern.:

'Beit known that I, WILLIAM H. SCOTT, a citizen of theUnited States, residing at St. Louis, Missouri, have invented a certain new and useful Improvementin Bolsters,of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specication, in which- Figure l'is a top plan view of the major portion of a bolster embodying my invention. Fig. 2 is a side elevational view of the same. Fig. 3 is a longitudinal vertical section taken centrally through Fig. 1. Fig. 4 is a horizontal sectional view taken on the line 4 4 of Fig. 2. Fig. 5 is a vertical section taken on the line 5 5 of Fig. 2, and Fig. Gis a fragmentary sectional view taken through the headblock substantially on the line of Fig. 3 with the parts separated for thepurpose of better illustration.

This invention relates to new and useful improvements in bolsters comprising a com! pression member, a tension member, a strut, and sectional head-blocks, the object of the invention being to produce a bolster of theA class described which Will be economical in manufacture and which will provide for a positive locking of the parts in coperative position.

Referring to the drawings, it will be noted that aside from the enlarged end 5 of the tension member the invention resides chiefly inthe construction of the 4head-blocks, and as said blocks are duplicates but one is illustrated herein.

A is the upper section of -the head-block,

which is provided with a transversely-extended seat l, upon which rests the web por-4 tion of the compression member C, and seats 2 areprovided for the flanges of said compression member. In the seat 1 is a laterallyextended opening through which may be block. In the section A is a seat 4 for the enlarged end 5 of the tension member D,

which enlarged end is heldin position therein by the head-block section B, which latter is provided with spring-seats 6, the section B resting within the lower hollow portion of section A and being provided with an inclined wall 7, upon which rests the tension member. .The'section A is provided with a lip or extension 8, adapted to extend over the end of the compression member C for the purpose of more securely locking thesamc in position. 4

The head-block sectionsare designed to be manufactured from malleable castings and are preferably cored out, as shown, so as to provide a proper Section to permit of the use of such castings.

Having thus described my invention, what' I claim as new, and desire to secure by Letters l. In a bolster, a compression member, a tension member, hollow head-blocks, and a member adapted to rest therein upon which inner member said tensionmember is adapted to rest; substantially as described. l

'block with seats for said enlarged ends, y,and

a memberwith inclined upper face below said tension member, bearing against said tension member; substantially as described.

4. In a bolster, a compression member, a tension member with an enlarged end, and a head-block provided with a seat for said com` pression member, which Seat forms an abutment for the enlarged ends of said tension member; substantially as described.

5. In a bolster, a compression member, a head-block with a seat for the compression member, a seat in said head-block beyond the end of the compression member, adapted to receive the end of a-tension member, a tension member with enlarged endportion', anda removable member adapted to lock said tension member in position; substantially as described.

6. In a bolster, a compression member, a tension member with enlarged end portions,

IOO

head-blocks with seats for said enlarged ends,

and spring-seat members adapted to lock said tension member in position in said seats substantially as described.

7. In a bolster, a hollow head-block with a seat, a tension. member with enlarged end adapted to rest therein, and a. spring-seat member adapted to lock said tension member in position; substantially as described.

8. In a bolster, a compression member, a tension member, a strut, telescopical headblocks, one of said head-blocks being provided With a seat for the compression meinber, and a seat for the tension member, and the other of said blocks being so formed as to hold said tension member in its seat; substantially as described.

9. In a bolster,the combination with a strut, a compression member, telescopical hend- Vb1ocks,zu1d a tension member which is clamped WILLIAM H. SCOTT.
